《21世紀(jì)中國新建筑記錄》 focuses on the 21st century Chinese architecture，including exploration of young arcnitects and the contemporary desigms of architectural institutes and CoIIeges，F(xiàn)oreign architectural practices in China，the construction of structures for the 0lympics and the Expo．a(chǎn)rchitectural clusters and architecturaI exhibitions．old building redevelopment，urban renewal，and post-disaster reconstruct on．Indeed．if we were to review the architecturaI history since 2000，an explorationof a deep-seated structure underlying various architecturaI phenomena by applying Foucault's method of“archeology”and“genealogy”would be preferable．but the work before us is a record of contemporary Chinese architectural phenomena；we should not jump to conclusions about the underlying structure，but try our best to contribute to the“archeology”of architectural knowledge．Of course，an architecturaI record of our collective memory also has an academic and historical value．

回顧核電廠抗震裕量評估方法的研究背景和發(fā)展歷程，并對其研究進(jìn)展及發(fā)展趨勢總結(jié)歸納，得出如下結(jié)論:

1) SMA 方法包括 NRC 法、EPRI 法和基于 PRA的 SMA 法 3 種，主要包括審查級地震確定、巡查/走訪、抗震能力分析和系統(tǒng)分析等內(nèi)容。NRC 法和EPRI 法評估目的相同，應(yīng)用廣泛?；?PRA 的SMA 方法可直接得到核電廠地震風(fēng)險水平，用于核電廠設(shè)計認(rèn)證。

2) SMA 法在國外的研究和實(shí)用中，時間較長，但仍存在保守性。運(yùn)用基于可靠度等精細(xì)化易損性分析方法，并采用合理的 CDFM 程序和參數(shù)取值，可以提高 SMA 分析結(jié)果的科學(xué)性。

3) 我國對 SMA 方法的研究與應(yīng)用起步較晚，亟需開展一些基礎(chǔ)性研究工作，包括: 確定審查級地震，建立數(shù)據(jù)庫，制定相關(guān)規(guī)范，建立核電廠合理模型，培養(yǎng)相關(guān)人才。 2100433B
